It is what

[0002]

2. Description of the Related Art One type of fishing rod reel is a so-called single bearing type reel. This type of reel is basically a base mounted on a fishing rod, and a spool spool rotatably supported by the base. It is composed of a ratchet mechanism and the like provided between the base and the spool. Examples of such reels include JP-B 26-1768, JP-B 55-41077, and JP-B 33-4576.

FIG. 11 shows a main part of a fishing rod reel described in Japanese Utility Model Publication No. 26-1768. In the figure, a is a base attached to a fishing rod by a leg member (not shown), b is a support shaft projecting from the center of the base a, and a bobbin spool (not shown) is rotatably supported on the support shaft b, and its central portion is A ratchet gear c is attached to the tip of a boss (not shown) that protrudes from the boss. d
Is a ring-shaped click spring, and has its mounting portion e fixed to the base a and lacking a position opposite to the mounting portion e, so that it has two left and right spring arms f, f. g
Is a ratchet pawl whose upper part is rotatably supported by the base a and is movable in the vertical direction, and the constricted middle part thereof is elastic end parts h, h of the spring arms f, f as shown by a solid line. Is selectively moved between a meshed position sandwiched by the two and a non-meshed position shown by a chain double-dashed line that is slightly higher than the meshed position. It is positioned so as to overlap with the teeth of the ratchet gear c. Therefore, in this state, the ratchet pawl g is pressed in the substantially left-right direction against the elastic force of the spring arms f, f in accordance with the rotation of the ratchet gear c, and the ratchet pawl g is engaged in the meshing position with the ratchet pawl g. The restoring force for returning to the gear is stored, whereby the teeth of the ratchet gear c are meshed with the ratchet pawl g one by one.

Reference numeral j denotes a switching lever, which includes a support shaft k rotatably supported by the base a, a check arm 1 located inside the base a, one end of which is fixed to the support shaft k, and a base. It is composed of an operating arm m which is located on the outer side of a and whose one end is fixed to the support shaft k. When the switching lever j is in the non-return position where the operating arm m is indicated by the two-dot chain line, the tip of the non-return arm 1 is in contact with the ratchet pawl g from the left side. The ratchet pawl g is prevented from rotating to the left, and therefore, in this state, the ratchet gear c and the spool (not shown) can rotate only in the clockwise direction toward the drawing. Further, when the switching lever j is moved to the non-return release position shown by the broken line, the non-return arm 1 is separated from the ratchet pawl g to some extent, so that the movement of the ratchet pawl g can be stopped. There is no. Therefore, in this mode, the spool can rotate in either direction.

[0005]

In such a fishing rod reel, it is necessary to precisely define the mounting position of the click spring d with respect to the base a. That is, if the elastic ends h of the click spring d do not come into proper contact with the predetermined position of the ratchet pawl g at the meshing position, the posture of the ratchet pawl g is tilted.
And the ratchet gear d cooperate with each other to cause a failure in the ratchet operation, and even when the switching lever j is moved to the non-return position, the non-return arm 1 may not properly contact the ratchet pawl g. This is because the movement of the ratchet claw g cannot be prevented and the check may not work properly. In this respect, the conventional fishing rod reel described above has the following problems. That is, in this reel for a fishing rod, the click spring d is attached
The holes (not shown) formed in the base a and the mounting holes n, n formed in the mounting portion e of the click spring d are fixed to the base a by the inserted rivets o, o. Unavoidable play of
Therefore, some adjustment has been forced. This is one of the reasons for increasing the man-hours of assembly work, and
There was a problem that the assembly quality was likely to be unstable. Further, there is also a problem that the rivets o and the fixation by o loosen with time.

[0006]

In order to solve the above-mentioned problems, the fishing rod reel of the present invention includes positioning elements for positioning the attachment portion of the click spring with respect to the base separately from the click spring and the base. It is provided.

[0007]

Therefore, in the fishing rod reel of the present invention, the position of the click spring with respect to the base is accurately defined by the positioning elements provided on the reel, so that the elastic end portion of the click spring has a predetermined position of the ratchet pawl. The position is properly contacted, and the ratchet operation by the ratchet pawl and the ratchet gear can be stably performed. Then
Assembling quality of the fishing rod reel is stable, and adjustment is not required for the assembly, especially for attaching the click spring to the base, so that the assembling work can be labor-saving. Even if the means fixed to the base may loosen, regardless of that,
The position of the click spring with respect to the base is held by the positioning element. Moreover, since the positioning element is separately provided with the base and the click spring, the number of parts does not increase and the cost does not increase.

[0008]

The support shaft 3 is rotatably inserted in the base 3, so that the spool 4 is rotatably supported by the base 2.

Reference numeral 9 denotes a ratchet gear, which cooperates with a ratchet pawl, which will be described later, to perform a click stop on the rotation of the bobbin spool 4 or to stop the rotation in one direction. The ratchet gear 9 has a spur gear shape having a diameter of about ¼ of the diameter of the spool 4 and has an insertion hole 9a formed at the center thereof.
Is substantially equal to the outer diameter of the bearing sleeve 8. A shallow circular recess 9b is formed in the center of one surface of the ratchet gear 9. Then, the insertion hole 9b
The end portion of the bearing sleeve 8 is inserted from the side opposite to the circular recessed portion 9b, and a portion 8a protruding from the insertion hole 9a of the end portion (hereinafter, referred to as "caulking portion") is shown in FIG. Is crimped so that the diameter is expanded. This allows
The center portion of the ratchet gear 9 is crimped onto the tip surface of the boss 7 by the caulking portion 8a of the bearing sleeve 8. Then
The ratchet gear 9 is fixed to the spool 4. The caulking portion 8a is positioned so as to be housed in the circular recess 9b of the ratchet gear 9.

Reference numeral 10 denotes a click spring supported by the base 2 for controlling a later-described ratchet pawl, and its respective parts are integrally formed of synthetic resin. That is, the click spring 10 has a circular band shape as a whole, and by omitting a part in the circumferential direction, two left and right symmetrical spring arms 11 and 11 extending so as to draw substantially semi-circular arcs are formed. Formed, these spring arms 1
A continuous portion 12 of 1 and 11 is a mounting portion. Therefore, the spring arms 11 and 11 have elastic flexibility such that the tip ends thereof are displaced substantially in the left-right direction. In addition, the spring arm 11,
The width of 11 is widened toward the mounting portion 12, and the mounting portion 12 is the widest in the click spring 10. Reference numerals 13 and 13 (see FIG. 4) are small protrusions (hereinafter, referred to as “elastic end portions”) protruding rearward from the tip ends of the spring arms 11 and 11. A relatively wide guide groove 14 extending in the up-down direction (the upward direction in FIG. 1 is upward) is formed in the middle of the front surface of the mounting portion 12, and the upper end of the position corresponding to the guide groove 14 is formed. A notch 15 having an open lower end is formed in the portion excluding the portion.

Numerals 16 and 16 are holes formed in both sides of the guide groove 14 in the mounting portion 12. Two narrow grooves 17 and 1 extending in the vertical direction are provided at positions on the rear surface of the mounting portion 12 that substantially correspond to the left and right side portions of the guide groove 14.
7 is formed, and substantially semicircular positioning projections 18, 18 are formed on both sides of the same.

At the lower end of the front surface 2a of the base 2, there are formed protrusions 19 having a U-shape that are open upward, and positioning protrusions 20 that extend in a substantially semi-circular shape are formed on both sides of the protrusions. 20 are formed. This positioning ridge 2
The reference numerals 0 and 20 have such a size that the positioning protrusions 18 and 18 of the click spring 10 can be fitted in the inside thereof. Insertion holes 21 and 21 are formed inside the positioning protrusions 20 and 20. Reference numeral 22 is an elongated hole which is formed in a position surrounded by the U-shaped protrusion 19 and which is long in the vertical direction.

The click spring 10 is attached to the base 2 as follows. That is, the positioning protrusions 18, 18 of the click spring 10 are replaced by the positioning protrusions 20, 20.
And the left and right sides of the U-shaped protrusion 19 are separately housed in the grooves 17 and 17 of the click spring 10, and in this state, the holes 16 and 16 of the click spring 10 and the insertion holes 21 and 21 of the base 2 are inserted. Matches each other. And these holes 1
6, 16 and insertion holes 21, 21 with stepped rivets 23, 2
3 is inserted from the rear, and its front end is crimped. As a result, the mounting portion 12 of the click spring 10 is fixed to the base 2. Therefore, the position and the posture of the click spring 10 on the base 2 are accurately defined by the positioning protrusions 18, 18 being fitted exactly in the positioning protrusions 20, 20.

In this state, the support shaft 3 is located substantially in the center of the inside of the click spring 10 when viewed from the front.
Reference numeral 24 denotes a gear receiving ridge formed on the front surface 2a of the base 2, which extends in an annular shape around the support shaft 3 when viewed from the front, and the diameter thereof is smaller than the diameter of the root circle of the ratchet gear 9. It is getting smaller.

Reference numeral 25 is a locker for maintaining the state where the spool spool 4 is supported by the support shaft 3. The locker 25 has a rectangular plate shape that is long in the up-down direction, and as shown in FIGS. 3 and 7, the upper half portion thereof is punched out so as to bend in a substantially V shape when viewed from the side. Then, the lock piece 25 is provided in the guide groove 1 of the click spring 10.
4, the operation shaft 2 is inserted into the elongated hole 22 of the base 2 and the notch 15 of the click spring 10 so as to be movable.
It is fixed to the front end portion of 6. Accordingly, the lock piece 25 is provided so as to be movable in the vertical direction within a certain range. Reference numeral 27 denotes a coil spring arranged in the elongated hole 22. The pressing force of the coil spring 27 urges the lock piece 25 to move upward.

The state in which the spool spool 4 is supported by the support shaft 3 is held by the locker 25. That is, while inserting the support shaft 3 through the bearing sleeve 8, the spool spool 4
Is pressed toward the base 2, the ratchet gear 9
The periphery of the circular recess 9b on the rear surface contacts the gear receiving projection 24 formed on the base 2 (see FIG. 7). At this time, the lock piece 25 is once pressed downward by the ratchet gear 9, and the ratchet gear 9 is brought into contact with the gear receiving projection 24 at substantially the same time as the ratchet gear 9 is brought into contact with the lock piece 25.
, Which causes the lock piece 25 to return upward.
As a result, the upper half of the locker 25 is attached to the ratchet gear 9
Since the bobbin spool 4 is positioned so as to overlap with the outer peripheral portion from the front, the bobbin spool 4 is prevented from coming off the support shaft 3. In this way, the spool 4 is rotatably held by the base 2, and in this state, the open surface of the spool 4 is closed by the base 2.
Is blocked by. When the operating shaft 26 is pressed downward, the lock piece 25 is released downward from the ratchet gear 9, so that the spool spool 4 can be pulled out from the support shaft 3 in this state.

The caulked portion 8 of the bearing sleeve 8
Since a is housed in the circular recess 9b of the ratchet gear 9, it does not contact the front surface 2a of the base 2. Especially,
As shown in FIG. 7, since the caulking portion 8a faces the space inside the gear receiving projection 24 of the base 2, there is no possibility that the caulking portion 8a will contact the base 2. Then
Regardless of how the caulking portion 8a is caulked, the caulking portion 8a does not come into contact with the base 2. Therefore, the facing distance between the base 2 and the bobbin spool 4 depends on the length of the boss 7 and the ratchet gear 9. It is defined only by the size of the member such as the plate thickness that can easily obtain the dimensional accuracy, and therefore the relative positional relationship such as the facing distance or the play between the base 2 and the spool spool 4 can be accurately measured. And it can be easily implemented.

Reference numeral 28 designates a ratchet pawl made of a metal plate, which is long in the vertical direction and has semicircular cutouts 29, 29 formed in the middle portions of its left and right side edges, and a portion 30 below the cutouts 29, 29. (Hereinafter, referred to as "meshing portion") is a substantially inverted triangle. Reference numeral 31 denotes a long hole formed in the base 2, which is long in the up-down direction and is provided at a position corresponding to between the elastic end portions 13 of the click spring 10 in the attached state. Reference numeral 32 denotes a pawl shaft, an operating head portion 32a is formed in a rear portion thereof, an intermediate portion thereof is inserted through the elongated hole 31, and a front end portion thereof is fixed to an upper portion of the ratchet pawl 28. As a result, the ratchet pawl 28 is supported by the base 2 so as to be vertically movable within a certain range and rotatable about the axis of the pawl shaft 32.

Such a ratchet pawl 28 has a meshing position shown in FIG. 5 (a position shown by a solid line in FIG. 7), that is, a position where the notches 29, 29 are engaged with the elastic ends 13, 13 of the click spring 10. The non-meshing position shown in FIG. 9 (the position shown by the chain double-dashed line in FIG. 7), that is, the position where the elastic end portions 13, 13 come in contact with the both side edges of the meshing portion 30 at the upper end of the moving range. It is selectively moved between. This movement is caused by the claw shaft 32.
This is performed by pressing the head 32a of the. Then, when the ratchet pawl 28 is in the meshing position, the movement locus of the meshing portion 30 overlaps with the teeth of the ratchet gear 9, and meshes with the teeth of the ratchet gear 9 unless it is pressed in the left-right direction. As described above, since the ratchet pawl 28 is elastically held at that position by being clamped by the spring arms 11, 11 of the click spring 10 in any position, When pressed in the direction, the restoring force for returning to the position where it meshes with the ratchet gear 9 is stored. When the ratchet pawl 28 is in the meshing position, the bobbin spool 4 rotates so that the teeth of the ratchet gear 9 move the ratchet pawl 28 to the spring arm 11,
Since the rotation is performed against the elastic force of 11, the rotation is appropriately suppressed, and a click sound is generated along with the rotation. The spool spool 4 can freely rotate when the ratchet pawl 28 is moved to the non-meshing position.

Reference numeral 33 is a mode switching mechanism. The mode switching mechanism 33 restricts the movement of the ratchet pawl 28 in one direction to selectively form a reverse rotation preventing mode in which the reverse rotation of the spool 4 is blocked and a reverse rotating mode in which the blocking is released. Therefore, it is composed of only two members, a switching lever and a lever support shaft that rotatably supports the switching lever. Reference numeral 34 is a switching lever, each part of which is integrally formed of a metal plate. That is, the switching lever 3
When viewed at the position shown in FIG. 5, 4 is an intermediate portion 35 extending substantially in the left-right direction, a relatively short working arm 36 extending counterclockwise from the right end thereof, and an intermediate portion 35 of the intermediate portion 35. A relatively short insertion part 37 protruding rearward from the left end and the insertion part 3
7 and an operating portion 38 that protrudes leftward from the rear end. Then, a small engaging protrusion 35a is formed at the center of the intermediate portion 35.
(See FIG. 10) is punched out rearward, and a hole 39 is formed at a corner where the intermediate portion 35 and the working arm 36 are continuous. Further, a substantially inverted V-shaped engaging notch 40 is formed at the tip of the working arm 36.

Reference numeral 41 denotes a hole formed in the base 2 at a position slightly separated from the long hole 31 through which the pawl shaft 32 is inserted to the left side, and 42 denotes an arc long hole extending around the hole 41. The insertion portion 37 of the switching lever 34 is inserted through the arcuate elongated hole 42. Reference numeral 43 denotes a rivet-shaped lever support shaft, a head portion 43a is formed on the rear portion thereof, and the shaft portion 43b is rotatably inserted through the hole 41, and
The part that protrudes forward through the hole 39 of the switching lever 34 is crimped. As a result, the switching lever 34 is rotatably supported by the base 2 via the lever support shaft 42.

It should be noted that small engaging recesses 44, 44 (only the lower engaging recess is shown in the drawing) are formed on the front surface 2a of the base 2 at positions corresponding to both ends of the arcuate elongated hole 42. The switching lever 34 has two engaging projections 35a engaged with the engaging recesses 44, 44 respectively.
You can apply a click stop at one position.

Therefore, in the state where the switching lever 34 is in the unlocked position shown in FIG. 5, that is, in the state where the engaging projection 35a is engaged with the upper one of the two engaging recesses 44, 44, Since the working arm 36 of the switching lever 34 is separated from the ratchet pawl 28 to the left side to some extent, the movement of the ratchet pawl 28 is not restricted. This state is a reversible mode, in which the spool 4 can rotate in any direction.

The reverse rotation stop of the spool spool 4 is performed as follows. That is, with the ratchet pawl 28 in the meshing position, the switching lever 34 is in the locking position shown in FIG.
When moved to a position that is engaged with the underside of 4,44,
The engagement notch 40 is engaged with a corner portion where the meshing portion 30 of the ratchet pawl 28 and the notch 29 on the left side are continuous, thereby preventing the ratchet pawl 28 from moving in the clockwise direction. This state is the reverse rotation prevention mode. In this mode, the ratchet gear 9 is prevented from rotating in the counterclockwise direction, so that the spool spool 4 can rotate only in the clockwise direction.

Reference numeral 45 denotes a mounting leg whose upper portion is fixed to the rear surface of the base 2, and the fishing rod reel 1 has this mounting leg 4.
It is attached to the fishing rod through 5.
